i have 2 models: basket and egg
each basket can contain some eggs.

i have urls like this

/basket/
/basket/1/update
/basket/1/delete
/basket/create
/basket/1/egg
/basket/1/egg/create
/basket/1/egg/1/update
/basket/1/egg/1/delete

there is no urlconf like
/egg/
/egg/create
/egg/1/update
/egg/1/delete

in view for /basket/1/egg/1/update i use hidden
field for Basket model.

The problem is that i can't set it's initial value to basket_id.
